rlhisinvention relates to machines for applying pressure to the bottoms of shoes, and is herein illustrated as embodied in a machine of that type in which the pressure is applied at onetime to all the vportions of the shoe bottom that are treated, by the pressing means, by use of a yieldable pressinggmem# ber or pad. The invention is also herein illustrated as applied to the shaping of the shank portions of outsoles Ain the manufacture of shoes of a type having both an outsole and an insole with the outsole'secured directly to the outer face of the margin ofthe upper overlying the insole; but it is to be understood that it is applicable to the' manufacture of shoes of various kinds including welt shoes and turn shoes. It is further to be understood that the invention is not limited to means for operating on the shank po-rtions of shoes, and that it is applicable to sole-laying operationsas well as to operations performed after the soles have been secured to other portions of the shoe materials.

Itis a characteristic of shoes of certain kinds or styles, especially of some womens shoes, that the shank portions of the soles have pronounced lateral curvatures and are provided with thin edges lying in close rela; tion to the uppers. For shaping the shank portion of the sole of a shoe of'that kind there are advantages in the use of pressing means that acts at one time on all the portions of the sole that it treats, as distinguished, for example, from a roll which is preferably, usedV at the forepart to shape that portion of the sole progressively, as explained in Letters Patent No. 1,790,191, granted on January 27, 1931, upon an application of E. E. Winkley.

In order to impart to thershank portion of` the sole the required lateralcurvature and to press its edges into close relation to the f upper, it is necessary in the use of such pressing ymeans that heavy pressure be applied at v the opposite sides of the shoe bottom in locations at and near the edgesof thesole. Ac-V cordingly, in one important aspect, an object of this invention is to provide pressing means of such a characteras vto produce improved results in respect to the application of pressure at the sides of the shoebottom. For

the purpose in view, the construction herein showncomprises a padholder having jopposite side portions arranged tosupport a pressingpad in locations opposite thebottomof a shoe to whichthe pressure is appliedand arranged to tip in response to the. pressureof the shoe on the-pad in such" manner as to caus-e an increase of pressure in the vicinity `of theside edges of the sole. lMore par'- ticularly,- in one aspect, the construction shown is suoli as to aiiord provision, bythe tippingof the opposite side portions of the padholder, forV an increase in the yield of portions of `the pad located midway vbetween the opposite side edges of the shoe bottom relatively to other portions of the pad, so that the shoe sinks farther into the Vp-ad than it Aotherwise Would, with resulting increase in the pressure at the sides of the shoe bottom. It isa further advantageous characteristic of the construction shown that by the tipping totheshoe and alsoa Lbendingofthe pad as a whole in such manner as to wrap itv aroundv the laterally convex surface ofthe shank portion ofthe shoe bottom. In these different ways a relative increase is effected in Vthe pressure of the pad in locations at and nevar the edges of the sole, soV that the sole is conformed effectively to the latterally convex contour of the bottom of theshank portion of thelast and its edges aregpressed close to the upper in the manner required for the best results.

VThe invention will in the claims.

the shoe, illustrating further the relation be tween the shoe and the parts that operate thereon.

The invention is illustrated as applied tov a machine of the same type as that disclosed in Letters la'tent No. 1,549,243, granted on August 11, 1925, upon an application of E. E. VVinkley, with portions of the machine constructed in accordance with the further disclosure of Lettersy Patent No; 1,7 90,192, grant'- ed on January 27, 1931`upon an application of E.' E. TvVinkley; although it is to be underi stood that the invention is not limited to ina- Ychines of that particular'type. Machines of the type referred to are twin machines,'com prising duplicate mechanisms whereby one -shoe is subjected to'pressur'e simultaneously with the vrelease from'pressure ofA 'another shoe previously operated upon. y Only one of such mechanisms is hereinillustrated or need be Vreferred to for an understanding of the present invention. As shown in Fig. 1, and

as more lfully illustrated in Letters Patent No.

1,549,243 above mentioned, the machine provided with a pair .of vertical rods 10 on which there is adjustably secured a casting 12 which serves as a support for downwardly extending arms 14 and 16 of a jack which supports the shoe againstthe upwardly directed pressure of the sole-pressing means. The arm 14 .is provided with "a pin 17 (Fig. 3) vfor engaging the heel end of the last in its spindle hole, and the arm 16 is provided with means of the same construction'as disclosed in the above-mentioned Letters Patent No. 1,790,192 for supporting the last and shoe along the instep and in the hollow'b-ack of the toe.

Mounted for vertical sliding movement on the rods 10 is 'a carrier 18 provided at its opposite sides with means for supporting a pair of trunnions 2O that are fast on a pad boX '22, this pad boX being provided 'with means more particularly hereinafter described for supporting f a pressing pad 24 whereby pressure is applied to the bottom vof the shoe. The means for imparting operative movement to the carrier 18 includes a link 276 and other mechanism not herein shown in detail, since it is fully disclosed in the aboveinentioned LettersPatent No. 1,549,243. It will be understood that the shoe is mounted on the jack by the operator when the carrier 18 is inits lowermostv position, and that in n the operation of the machine the carrier and the shoe-pressing means supported ythereon are moved upwardly to apply the pressure to the shoe, after which the machine comes autovina-tically to rest. In the next operation of the lmachine the shoe `is released by downward movement of the carrier 18 simultaneouslywith the application Vof pressure to another shoe by the other twin mechanism.

The invention is illustrated by reference :to a sole-pressing operationA` performed'mainly on the shank portion of the bottom of a` -to engage aside face ofthe pad.

womans shoe having characteristics such as hereinbefore described, the arrangement of the jack parts 14 and 16 and of the pressing means being such that the pressure is applied in a direction inclined somewhat forwardly towardthe forepart of the shoe, in general similarity to the disclosure of Letters Patent No. 1,790,192. The bottom of the shank portion of the last, vas illustrated, has a pronounced lateral curvature, ai'idthe'y outsole Vhas comparatively'thin enges which should pivotally supported onv the pad box 22 by f means of rods 30 located at the opposite sides of the pad 24 Vnear the top of the pad,so that .each sideV portion 28 may tip relatively tothe other about an axis extending lengthwise of the shoe, the arrangement shown being such f that the tipping movements occur in response to pressure of the shoe on the pad and against the resistance of springs 32 mounted inthe padv boxy 22 and engaging arms 34 on the 'members' 28. Preferably each member 28 is provided with two arms 34 in engagement with separate springs-32,v and each spring at its outer end is/seated on yan abutment screw 36 in the pad box whereby its tension may be varied. Initially the springs 32 position 1 the two halves 28 of the pad holder in abutting` relation to each other with the portions that underlie thepad in thesame plane, and in the sole-pressing operation the springs yield moreor less in response to such tipping movements of the parts 28 as occur in respense to pressure of the shoe on the padV 24.

The pad 24 is preferably made of rubber'y with a leather cover on its shoe-engaging face, as common heretofore, and it may, as i. illustrated, be shapedto approximate more or less closely the contour of the portions of theshoe bottom on which it is to operate, in accordaiicealso with prior practice.

, By reference to Fig. 2 it will be seen that with the rods 8() located as shown near. the

top of .the pad 24at its opposite sides, the

tipping movements of the'members 28 of the pad holder result ina lowering of the .portions o f the holder which are under the central portion of the pad relatively to other portions, in relative separation widthwise of the shoe of the lower portions of the members 28, and .in some relative movement toward 'each other of the extremeupper portions of the members 28 atthe-sides ofthe pad. Consequently, the construction disclosed v'pro` vides for increase in the yield of portions ofl the pad located centrally under the shoe bottom relatively to other portions, both by reason of the lowering of the intermediate portions of the pad `holder and by reason of the greater room afforded for lateral expansion of the lower vportions of the rubber pad, so

that the shoe is permitted to sink farther into the pad than it otherwise would, with a resulting increase in the pressure applied in the vicinity of the side edges of thesole. Furf thermore, the inward tipping movements "of the upper portions of the `members 28 at the sidesof the'l padresult in more or less lateral different ways there is produced a relative increase in the amount of pressure applied tothe sole adjacent to its opposite side edges while adequate pressure is still maintained on other portions of the sole, sov that insur-.

ance is afforded that-the sole will be shaped properly in conformity tothe curvature ofv the bottom, of thelast and that its oppositev side edgeswill be pressed into the ,desiredv close relation to the upper.

It is to be understood that the invention is not limited to' a construction in which they Having thus described my invention, what I claim as new and desire to secure by Letters Patent'of the United States is:
